Comparing the Effectiveness of Nutritional Education with and without Physical Activity on Blood Lipids and Liver Aminotransferase Enzymes in Non-Alcoholic Fatty Liver Diseased Men

Aims: Fatty liver disease is a type of fat accumulation in the liver parenchyma that can be related to lifestyle. Therefore, this study compared the effectiveness of nutrition education with and without physical activity on blood lipids and liver aminotransferase enzymes in men with non-alcoholic fatty liver disease. Materials Methods: This study is a randomized clinical trial with a control group, carried out on 80 employees working in the South Pars gas complex in Jam, Iran, suffering from fatty liver. The participants were allocated to four nutrition education groups; a physical activity group, a nutrition education group with physical activity, an education group without physical activity, and a control group (20 people each) using a random block sampling method. In all four groups, 48 hours before the intervention, 3 and 6 months after the intervention, blood lipids and liver enzymes were measured and recorded in a form. Data were analyzed using SPSS 21 software and chi-score statistics, one-way ANOVA, and repeated measures ANOVA test. Findings: Alanine aminotransferase enzyme showed a significant improvement in each of the 3 intervention groups compared to the control group at 3 and 6 months after the research intervention (p=0.001). Low-density lipoprotein showed a significant improvement in 6 months, which was related to the group of physical activity combined with nutrition education (p=0.005). Conclusion: Exercise and education interventions are more effective over a longer period of time in preventing and treating non-alcoholic fatty liver disease.
